McKissick 435 Series Snatch Block - 25 Ton - 1 to 1-1/4 in Wire Rope - 8 in Sheave - Roller Bearing

Description du produit

The McKissick 435 Series Snatch Block is a heavy-duty wire rope snatch block engineered for demanding high-capacity rigging, lifting, and load-redirecting applications. Designed for use in heavy industrial, construction, oilfield, and marine environments, the 435 Series represents McKissick's offering at the upper end of the snatch block load range, built to deliver reliable performance under sustained high-load conditions where lesser blocks would be unsuitable.

This block is rated for a 25 ton load capacity and is designed to accommodate wire rope cable ranging from 1 in to 1-1/4 in in diameter. The 8 in outside diameter sheave is supported by a roller bearing, which reduces friction during operation, promotes smoother cable travel, and contributes to lower wear on both the wire rope and the sheave under sustained high-load use. The overall height of 688 mm is more compact than the 930 mm height of the 30 ton, 12 in sheave variant in the 435 Series, and this dimension should be carefully verified against available rigging clearances and hook or shackle attachment hardware prior to use. The smaller 8 in sheave outside diameter at the 1 to 1-1/4 in cable range results in a tighter wire rope bending ratio compared to larger sheave options and should be evaluated against the wire rope manufacturer's minimum bending ratio recommendations before use.

The 435 Series snatch block is well suited to applications requiring load redirection, mechanical advantage in heavy rigging systems, or pulling operations where a high-capacity, roller-bearing-equipped block is required. Its design supports use in heavy construction, offshore and oilfield rigging, marine lifting, and other industrial environments where performance at the 25 ton load rating is essential and wire rope diameters in the 1 in to 1-1/4 in range are standard.

Note:

Material composition and finish details should be confirmed against the official McKissick 435 Series product documentation or catalog prior to specification. The 1 to 1-1/4 in cable diameter range should be verified against the wire rope installed in the rigging system before use. The 8 in sheave outside diameter results in a tighter wire rope bending ratio at the 1 to 1-1/4 in cable range and should be evaluated against the wire rope manufacturer's minimum bending ratio recommendations before use. All attachment hardware — hooks, shackles, and swivels — must be rated at or above the 25 ton load capacity of this block. The 688 mm height should be verified against available rigging clearance before use. At the 25 ton load rating, all rigging components in the system must be rated and inspected to match or exceed this capacity. Do not assume certifications or standards compliance without verification from McKissick or an authorized distributor.
